My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, in which I have illustrated the machine which I find best suited to the purposes of the invention.

The apparatus or mechanism herein illust 'ated is an automatic weaving machine that I have devised for carrying out my inprovement in the art of weaving coiled wire fabrics. Only such parts of the mechanism are shown as will be helpful in describing and understanding the present invention.

The complete machine constitutes the subject matter of my companion application, Serial No. 468,388, filed December 19, 1908, in which it is fully set forth and claimed. This particular machine operates in conformity with my novel method or process and is adapted to add four coils to the fabric at each operation. By slight modification it may be adapted to the simplified performance of my invention, by which but two coils are added at a time and likewise, by modification, it may be adapted to handle a greater number of coils.

In the drawings, A, represents the table or frame of the machine. On the table is a long channel or coil receiver, B, in which the weaving operation takes place.

0, b and b are respectively the front and back walls and bottom of the channel.

Z)" and b are spacing or escapement bars in the bottom of the channel, the former be ing supported by springs, 6 and the latter being arranged for operation by arms, [9 The arms, Z2 take motion from the rocking shaft, B on the back of the machine.

C is a member which partially closes the channel, B. It is provided with a V or knife edge, .C, and is hereinafter referred to as the channel closure or knife edge. By means of mechanism, 0 the knife edge is periodically moved back and forth across the channel.

D is a member having a large number of pins, ti, which pass through the side, I), of the channel and extend across the channel. These pins, (Z, serve to secure and space the turns of the coils in the channel. A mechanism, d periodically moves the pins transversely in the channel. A member, E, bears a number of short bars or fingers, e, which extend through or across the wall, I), of the channel and are adapted to be projected across the same to shift certain coils therein. Guide pins, (Ze, serve to support the members, D and E. A mechanism, 6 is employed for moving the member, E. The shaft, 6 is a part of the mechanism, 0 and is operated by the lever, e. A shaft, CD, actuated by a lever, cd, is the means employed for operating the parts, 0 and (Z the arrangement being such that the closure, 0, moves at a more rapid rate and through a greater distance than the pins, d.

F is a knife head bearing a plurality of cutting knives, f, for severing the coils in the channel. It is operated by a lever, F.

G, G, G, are coil guides, in the receiving end of the channel. These guides serve to space the coils apart in the channel. Their ends co-act with the knives, f.

represents a bank of coilers adjacent to the receiving end of the channel. In this machine I employ five coilers, if, 71 h 71 and h. The first four are used in weaving the fabric'and the fifth coiler, h is used in forming the cords in the fabric. Five wires extend from five reels, I, to respective coilers, the same passing over the interposed sheaves 2'.

J is a wire propelling head which is arranged between the coilers and the sheaves, 2', containing driving rolls which force the wires through the coilers. A pair of driving rolls, j, j, is provided for each wire and these rolls are so arranged that, while in rotation, they may be separated to free the wire and cease the propulsion thereof through the coiler, or may be forced upon or against the wire, to drive the same through the coiler.

A mechanism which operates in time with the knives and the moving members of the weaving channel, periodically closes the rolls together to run coils into the channel and then opens or spreads the rolls to stop the wires and give time for the operation of the knives and channel members. A pattern mechanism associated therewith, at longer periods, interrupts the channel operations, throws several of the pairs of rolls out of action and causes the repeated operation of one or more pairs of rolls, to form a cord in the fabric. The mechanisms by which these operations are brought about will be best understood by reference to Figs. 1 to 5 inclusive. On the table, A, are standards, 7' which contain bearings for the two shafts,

and The lower shaft, j, is driven continuously by gearing, K; the upper shaft is not driven being simply a guide and stop part. The rolls, j, are fastened to the shaft, j, and therefore rotate continuously. Each of the upper rolls is carried by its own lever, j. The levers are pivoted on the cross rod, and at their free ends are attached to springs, j. These springs tend to force the rolls together. The pairs of rolls are joined by gears, 77, whereby the lower roll drives the upper roll in each case. it shaft, j carried by the standards is equipped with a plurality of arms or cams, j", one for each lever, j. Mechanism, L, connected with the shaft, by the linlt, j and the lever, j operates the cams, j", periodically to separate the rolls in advance of the operation of the knife head, F, and close them together after the operation of the channel parts. The pattern mechanism, whereof, j, is the operating connection, includes the rock shaft, j, and its cams, j, j, j and j These cams engage corresponding arms, The cams, j, are disengaged from their arms when the cam, f is raised or engaged with its arm and vice versa. The rocking shaft, j, operates regularly, whereas the I rocking shaft, j, operates only at times; when cords are to be formed or have been 1 finished. hese times are determined by a pattern cam, not shown, and mechanism which is associated with the cam interrupts the action of the parts, C, l) and E, until the cord is completed.

it will be understood that during the cording period, the knife head, 1*, the driving rolls, and the wire stopping and starting shaft, continue in regular operation. in the present machine the pattern shaft, 7', normally holds in elevated position the lever of the driving rolls corresponding to the fifth coiler, h affected by the rocking of the shaft, j will be noted that the lever belonging to the rolls of the coiler, 7i}, not represented by a cam on the shaft, j. .Vhen the pattern shaft, j, is turned, it lowers the lever of the fifth pair of rolls (belonging to coiler, h and raises the levers of the first three pairs, 2'.

shaft is restored the fourth and fifth levers and their rolls take up the normal operation together, while the remaining levers and rolls remain idle. Thus by stopping three of the pairs of rolls, by throwing the channel members out of action and by putting two sets of rolls into action, I am able to run in the number of coils which may be required to During the regular operation of the machine and at the beginning of its cycle of movements, the parts occupy the positions shown in Fig. 1. At such moment the knives are raised or out of action, and the pairs of rolls belonging to the coilcrs, h it", 71 and 71 are in action, '2. 0., coils are being run into the channel.

Lin instant later, coils of proper length having been run into the channel, the mechanism L, moves the shaft, j and separating the rolls causes the stoppage of the wires in the coilers. This is followed by the cutoff ac tion of the knife he" d, h. Then the members D and C are drawn back by the rocking of the shaft, Cl), to free the new "ection of fabric which has been formed in the channel, in the manner more fully defined hereinafter. The fabric having been freed, the members, C and D, return to position and the member, E, moves forward to shift the Having done this the member, E, returns to the position shown in Fig. l, marking the end of the cycle; the mechanism, L, immediately thereafter restoring the rolls to engagement with the wires, to institute the coil forming step or stage of the next cycle. The pattern mechanism may begin its operation at the end of this coil-formin stage in some cycle (as predetermined by the form of the pattern cam). The channel members and the first three driving rolls (and coilers, if, 715 and 725') having been thrown out of step (as before described) the last two rolls (and coilers, it and fa are operated one or more times, (according to the pattern), to run or weave two or more additional coils in the section of fabric then lying in the channel. Following the formation of a cord in this manner, the channel members, C, l), and E operate (in the manner before described) to release the fabric and position the reserve coils, preparatory to the next regular cycle 1 of movements. its arm therefore is notf it The character and operation of the mechanism being now understood, the process which is performed thereby may be described and will be best understood upon reference to Figs. 8 to 18. These are diagrammatic views in which I have depicted the several principal and intermediate steps or stages of the invention. Figs. 8 and 13 show the channel, B, and the parts C, d, c, b and b", in the relation or positions occupied, at the instant following the liberation of a C, and the pins, cl, have returned to normal positions and before the coil transferring fingers, e, have operated. For clearness the knife edge is omitted in Fig. 13. The coils, 1 (dotted lines Fig. 8) represent the body of the fabric, which rises from the channel, being held in such position by slight tension from above. The lowest or edge coil of the fabric is marked 1. This coil is held in the channel by the knife edge, G, and the pins, (Z. The reserve coils are indicated by the numerals 2 and 3. The coil 1 and the reserve coils 2 and 3 are at opposite sides of the channel and are separated by the members, 5 and b Coils 2 and 3 are interlocked with the pins, d, and they are also relatively interlocked; being at this time substantially coincident (as to their axes) and one being a half pitch or turn in advance of the other. It may be here explained that the coilers, 71, h and the guide, G, are formed to weave the coils 2 and 3 in this manner. It should also be noted that the coil, 2, is parallel to the edge coil, 1, whereas the coil, 3, is not parallel, being a half turn out of line or step with respect to the edge coil. Having positioned the coils, 1, 2 and 3 in this manner, I next transfer the coils 2 and 3 across the channel, and set or leave the coil, 2, along-side of or against the edge coil, 1, 2'. e. I nest the coils 1 and 2 by placing them in parallelism and substantial contact, so that their spirals are substantially parallel. This I do by means of the fingers, c, which being moved forward, as shown in F 9 and 1* engage the coil 2, and push the same over the bars, 5* and 6 The coil, 3, being interlocked wit-h the coil, 2, is transferred with it. The bar, 79 prevents the accidental displacement of the reserve coils in the channel, and being spring supported, yields to the passage of the coils under the propulsion of the fingers, e. The member, is positively supported and is positively retracted during the transference of the coils. It is held down until the coil, 2, passes over it and is then restored to raised position to hold the coil, 2, in engagement with coil, 1, and to spread the coils, 2 and 3, as shown in Figs. 9 and 14; this last being a precaution against the accidental interlocking of the coil, 3, with the edge coil, 1, by the coupling coil about to be described.

After the fingers, e, have transferred the coils as depicted in Fig. 1%, they are returned to normal position as shown in Fig. 14*, the coils remaining as there shown. I have hereinbefore described the cycle of operations as beginning with the running of the four coils. This step is depicted in Figs. 10, 15 and 15 and begins after the coils, 1, 2 and 3 have been juxtapositioned in the manner next above described and shown in Figs. 9, 14 and 14 The four coils alluded to are the coils 4 and 5 and the coils, 2 and 3.

These coils are woven as shown in Fig. 15 and the new reserve coils 2, 3, obviously occupy the position vacated by the preceding reserve coils, 2 and 3. The coil, 4, is the interlocking or coupling coil, and runs in the portion of the channel between the member, I), and the wall, 5 It is a half-pitch or turn behind the parallel, juxtapositioned coils 1 and 2 and serves to interlock them, as clearly shown in Figs. 10 and 15. The coil, 5, runs in the portion of the channel between the members, btand b and interlocks with the coil, 3 g and as the coil 5, is to become the edge coil of the fabric its relation to the pins, (Z, and the other coils correspond to that of the coil 1.

Fig. 15 depicts the completion of the running or weaving of the coils, 4, 5, 2 and 3. Obviously the running in of coils 4 and 5 adds four coils to the edge of the fabric, inasmuch as the coil, 4, attaches the coils, 2 and 3 to the coil, 1, and the coil, 5, is attached to or interlocked with the coil, 3. The cycle of operations is most conveniently described as beginning with the simultaneous running in of the four coils, but from another view point the addition of four new coils to the fabric may be said to begin with the moving over of the reserve coils and to end with the running in of the coils, 4 and 5, the running of the new reserve coils, 2 and 3, being in this sense a preparatory or incidental step. Immediately after run ning in the coils, 4:, 5, 2 and 3, I withdraw the newly completed portion of the fabric from the channel, as depicted in Figs. 11 and 16. This is accomplished by retracting the pins, d, and the knife edge or closure, C. As these parts are drawn back, successive coils, 1, l, 2 and 3, are released and as the fabric 1 is under tension, the coils are lifted out of the channel. The parts, d and C are not drawn back far enough to release the coil, 5, but co-act with the member, I)", to retain it in the channel. It will be evident that the reserve coils, 2 and 3, are not disturbed by the movement of the parts C and (Z. Upon releasing the coils, 1, 2 and 3, I transfer the coil, 5, to the portion of the channel previously occupied by the coil 1. For this purpose the member, If, is retracted, and the pins, (1, and the member, C, are restored to normal position. The pins, in moving, carry the coil, 5, across the channel and against the wall, 5 thereof. The channel parts and the coils will then present the appearance shown in Figs. 12 and 17 For the sake of clearness I have marked the last coil, 51 in Figs. 12 and 17, to show that it is the coil previously referred to as coil, 5, but has become the new edge coil, 1. This point or stage may be termed the end of the weaving process, inasmuch as the coils, 5-1, and 2, 3, occupy the positions first described with the coils, 1, 2 and 3 and the adjacent coil. 2.

in Fig. 8. But in the other sense, above r'eferred to, the cycle or process may be said 1 to be still unfinished and not completed until the new reserve coils, 2" and -3 have been moved over against the edge coil in the manner depicted in Fig. 9; in which position the coils and the channel are in readiness to receive four new coils. Both ways of viewing and defining the inventions are obviously correct. The latter is perhaps the 3 most convenient when considering that phase of the invention which includes the cording of the fabric, for this step takes place preferably after the steps depicted in Figs. 9 and 10. In other words, after running in the four new coils as shown in F 10, I interrupt the sequence of operations depicted in Figs. l0, l1 and 12, and interpose the cording step. To do this I leave the parts in the positions of Figs. 10 and 15 and stopping the operation of the coilers which furnish the coils, 5, 2 and 3, run in additional coupling coils from the coilers, h and if. These coils become the coils, Al (see Fig. 18) and with the previous coil, l, constitute the cord; all being interposed between and interlocked with the edge coil, 1,

it must now be evident that my invention is capable of considerable modification. For example, the edge coil of the fabric may be held and a single reserve coil may be pushed against it, or vice-verse, and then a single coupling coil may be run in simultaneously with the placement of a new reserve coil; thus adding two coils to the fabric at a time. Again it is a simple matter to increase the fabric three coils at a time by simply omitting the coil, 5, and providing for the proper placement and relation of the .then terminal coil. 3, and the new reserve coil, It is obvious also that more than two reserve coils may be simultaneously formed and moved over for attachment to the edge coil; and also, several interlocked coils may be added to or take the place of the added coil, lt will also be obvious that my invention perform-able with multiple coils, in which case two or more coils take the place of each or any one single coil hereinbefore described. As these and other modifications of my invention will readily suggest themselves to one who is skilled in the a t, I do not conline the invention to the specific steps, processes or modifications herein illustrated and described. I desire also that it be under l stood that the invention is in no wise limited to the hereindescribed mechanism but may be carried out manually and by the use of mechanical aids of many kinds.
